We study the global analysis for parton distributions as a function of the QCD strong coupling strength alpha(s), and present a new series of distributions that span the range 0.110 < alpha(s)(m(Z)) < 0.128. We use these distributions to explore the correlation between alpha(s) and the gluon distribution; the viability of global analysis as a method to measure alpha(s); and the dependence on alpha(s) of predictions for W, Z, inclusive jet, and Higgs boson production (bb -> H and gg -> H) cross sections at the Tevatron and the LHC. We find that the uncertainty in alpha(s) is the dominant source of uncertainty for inclusive jet production at moderately small p(T) and for Higgs production at intermediate masses in the Standard Model.
